Abstract

Various embodiments relate to combined heat and power (CHP) systems. A CHP system can include a turbine system, a turbocharger system, and a refrigeration system. The refrigeration system can receive combustion products from the turbine system and compressed air from the turbocharger system. The refrigeration system can cool the combustion products and the compressed air to generate a cooled combustion product mixture that is provided to the turbine system.

a refrigeration system comprising a hot gas heat exchanger and a cold gas heat exchanger, wherein the refrigeration system receives combustion products from the turbine system and compressed air from the turbocharger system;
wherein the refrigeration system cools the combustion products and the compressed air to generate a cooled combustion product mixture that is provided to the turbine system; and
wherein the refrigeration system further generates steam that is provided to the turbine system.

2. The CHP system of claim 1 , wherein the cooled combustion product mixture is provided to the high pressure compressor of the turbine system.

3. The CHP system of claim 1 , wherein the steam is provided to the recuperator of the turbine system.

4. The CHP system of claim 1 , wherein the combustion products from the turbine system are received at the hot gas heat exchanger of the refrigeration system.

6. The CHP system of claim 1 , further comprising a warm gas heat exchanger that receives water from a pump, wherein the warm gas heat exchanger heats the water and provides the heated water to the hot gas heat exchanger in order to generate the steam.

7. The CHP system of claim 1 , further comprising a pump that is associated with the refrigeration system, wherein the pump provides cold water to a warm gas heat exchanger that heats the cold water.

8. A combined heat and power (CHP) system, comprising:
a turbine system;
a turbocharger system; and
a refrigeration system that receives combustion products from the turbine system and compressed air from the turbocharger system;
wherein the refrigeration system cools the combustion products and the compressed air to generate a cooled combustion product mixture that is provided to the turbine system; and
wherein the refrigeration system further provides water in at least one of liquid or gaseous form to the turbine system.

9. The CHP system of claim 8 , wherein the cooled combustion product mixture is provided to a high pressure compressor of the turbine system.

10. The CHP system of claim 8 , wherein the water is provided to a recuperator of the turbine system.
